Radio waves are a specific wavelength/band of the EM spectrum. Light is not radio waves, just as radiowaves aren’t light.
They’re both electromagnetic waves.

2mA minimum, and that’s just q current. It’s gonna be much higher when you’re actually using it for a clock.
I’m sure the casio’s main power sink is the display. I bet the refresh rate could be reduced for better battery life.

Science has an unintuitive philosophical system, it is actually impossible (or just not feasible) to “disprove” a lot of things absolutely 100%.
Best you can do is prove something, or fail to prove something.
And it does make some sense, there’s uncertainty in measurements, there’s some probability and statistics involved.
Proving there are NOT aliens out there would require checking every inch of every planet for life, remains, or fossils.

- Comment on Something Bizarre Is Happening to People Who Use ChatGPT a Lot 3 weeks ago:
People also don’t realize how incredibly stupid humans can be. I don’t mean that in a judgemental or moral kind of way, I mean that the educational system has failed a lot of people.
There’s some % of people that could use AI for every decision in their lives and the outcome would be the same or better.
That’s even more terrifying IMO.

- Comment on Why most countries are struggling to shut down 2G. 1 month ago:
There’s a lot of hidden cost associated with supporting legacy features/standards/technology
Do they have different frequencies? Require different antennas?
Are there cost implications for radios / amplifiers? Do ASICs support only newer modes? How much obsoleted / legacy HW is required?
And that’s just from a manufacturer standpoint.
Are more licenses required? Or other regulatory impacts?

0.08mg per half cup serving, but may vary depending on water used.
10mg is the accepted daily upper limit. So 62.5 cups of oatmeal to reach that max safe limit.
Acute poisoning symptoms may appear as low as 10-15 mg/kg, lethal dose might be 32-64 mg/kg.
So 200 to 400 cups of oatmeal per kg you weigh for a lethal dose.
